Legal Question in Wills and Trusts in Nevada

If the bank account is joint with step brother and father or payable on death to step brother, you can't do anything. Otherwise, give a certified copy of your father's death certificate to the bank so that they will know he has died and freeze the account.

As to personal possessions without a title such as guns, jewelry, coins, gold, silver, etc., if you think there is anything of that nature of substantial value you can file to open a probate estate. However, this will cost you, probably a few thousand dollars to start. I, and most attorneys I know, would not want to open a probate estate on the mere chance that there is something valuable there without a considerable upfront retainer.
